The aim of this research is to conduct an analysis of qualitative and quantitative studies on applying thesauri to the construction and development of ontologies and the identification of subject domains. We will investigate the approaches and methods used in these studies.

This descriptive-analytical research was conducted following the seven stages of systematic review suggested by Petticrew and Roberts (2008). Data analysis and visualization were facilitated using the DatawRapper software.

The analysis of studies in the area of applying thesauri in the construction and development of ontologies, while identifying and presenting the subject trends of studies, frequency, methods, languages and approaches, showed that the studies in this area include six main topics as follows: applying thesauri in the construction and development of ontologies in connection with multilingual information retrieval, applying thesauri in the construction and development of ontologies to cover a specific subject domain, applying the ISO 25964 standard in the development of ontologies using thesauri, presenting the framework, methods and tools for the use of thesauri in construction and development of ontologies, improving semantic relations and concept mapping using thesauri in the construction and development of ontologies and review studies of thesauri conversion to ontologies. 

Various subject domains, across different time periods, have benefited from applying thesauri for the construction and development of ontologies. Thesauri, as semantic tools, have provided the context for organizing, retrieving and accessing information more accurately and easily for stakeholders and applicants across various domains. Despite these advancements, the lack of a standardized and consensual framework, coupled with the need to update methods, approaches, and tools due to the reliance on natural language processing (NLP) technologies and knowledge engineering, has necessitated further research to mature this field.

Information fusion is a vital process in information management systems, which aims to merge information from multiple sources to provide a more comprehensive and accurate view of specialized domain. In structured information management systems, there are several methods for aggregating, consolidating, and fusioning information, but their approaches have not yet provided a clear pattern. The aim of the current research is to explain the concept and appropriate models of information fusion in information management systems and its use in relationship-based databases such as thesaurus. The research method is a conceptual type with ananalytical approach. The research population consisted of texts and outputs in the field of information fusion. The data collected by the library method. The findings showed that information fusion models are in four general categories of models based on information flow, workflow and activity, roles and functions of entities, and understanding concepts. The Omnibus workflow and activity model and the model based on the roles and functions of Endsley's entity as selected models according to the basic JDL are suitable for use in relationship-based information management systems such as thesauruses and ontologies, and they have the ability to be used with some changes. The main disadvantage of the reviewed information fusion models is not paying attention to the characteristics of specific information structures such as thesauruses. Not considering role of expert users in information systems based on user decisions that have the task of extracting specialized information and ignoring the collective participation system to solve complex problems, including finding similarities and solving it in the mass of information, not describing the required functions to solve the problems, managing the effects in case of system or user errors and restoring fusioned and consolidated information, as well as non-implementation of methods with operational examples in such structures, can be counted among these problems. In general, in each model of information fusion in information management systems based on thesaurus, the general processes of finding similarities, examining similarities, aggregating parameters and information fusion and managing the effectiveness of sub-systems should be considered. Unlike traditional information fusion methods that focus more on merge data, semantic information fusion emphasizes fusioning related knowledge and concepts stored in thesauruses instead of merging data and information. Therefore, it is suggested to pay attention to Semantic approaches in the process of integrating and fusion new models.

The purpose of this article is to present a plan to create coherence between thesauruses and specialized vocabulary compiled in IranDoc in the form of a meta-thesaurus. A meta-thesaurus is a cohesive combination of structured or controlled languages or compiled thesauruses and document lists that are obtained by linking, merging, and combining them. In this mechanism, in order to integrate the developed thesauri, each concept in a thesaurus is linked to the closest equivalent concept in other thesauri with the help of markers. In the process of communication between concepts, it is possible to translate the user query in the form of a systematic and comprehensive search of databases organized by various thesauruses and provides a platform for increasing comprehensiveness in information retrieval. In IranDoc, specialized thesauruses have been compiled in the 2001-2010 and updated in the years 2017-18. In addition, a collection of specialized dictionaries and vocabularies have been compiled and published. It is necessary to combine these words and thesauruses with each other in order to prevent the false loss of information in the search of Iran›s scientific database (Ganj) and to provide targeted access to specialized information. This article examines and analyzes various sources in the formation of meta-thesaurus in identifying related concepts, expressing the application and also the steps of its compilation.

Provide learning content in a pictorial thesaurus format to increase learning in students is the hypothesis that in this article was studied. This study showed that: 1) we can provide learning content in a thesaurus format, and 2) This format can be effective as an educational media in science education that leads to increase learning in students.  In this study, as a case study, the first year of high school chemistry book was selected. Then all the concepts and issues in this book was presented in the form of a pictorial thesaurus. Then by two statistical methods (test and survey), comments and scores of the test and control groups in some of Tehran schools were measured. The results of field activities confirm the hypothesis of increased learning due to the pictorial thesaurus. Thesaurus format benefits include concision, looking from above to the subject, reminded subjects taught before, classification and organization of educational content, ease of intuition of concepts, quick access to desired content, virtual education and distance learning.

To determine and explain the degree of compatibility of the structure and characteristics of Islamic sciences thesauri with the retrieval thesauri based on standard ISO 25964.

The present study is applied in terms of purpose and survey-analytical research method. The data collection tool is a researcher-made checklist. The research population includes descriptors of Islamic science thesauri. To analyze the data, descriptive statistics such as mean and standard deviation and in inferential statistics section, one-sample t-test, Friedman test and Kolmokrov-Smirnov test with the help of SPSS software were used.

Based on the data, the highest rate of conformity with the standard was seen in the display manner with an average of 80.87%, followed by the depth of semantic relations with a total average of 70.00%, Proximity of terms in natural language with an average of 24.12%, the degree of concordance of non-preferred terms related to each preferred term (22.25%), Quantity and content of domain notes (19.87%), and The lowest level of conformity to the expressive part of the signs indicating relationships (19.37%).

The results showed that the Islamic Sciences thesauri were in high level of compliance with the standard of Retrieval thesauri. Based on the findings, there is a significant difference between the structure and characteristics of Islamic thesauri and retrieval thesauri.

The aim of this research is to present the methodology for designing and constructing ontologies by reviewing approaches, tools and languages for ontology design. The results of this study were implemented in the design of an ontology named Asfaont in the domain of Indexing in LIS. By reviewing approaches, methods and languages, this paper explains the methodology of designing the Asfaont, its abilities and capabilities for representing and retrieving knowledge. The Asfaont is a reengineering of Asfa thesaurus.

This study was carried out to determine the level of precision, recall, and searching time for “Nama” and “Namayeh” databases, as well as to find out which of the indexing tools (thesaurus and Dewey decimal classification) helps us more in improvement of information retrieval. This study is an analytical survey in which the necessary data was collected by direct observation of the resources in “Nama” and “Namayeh” paper databases. The population under study included the articles which were indexed in both “Nama” and “Namayeh” databases in the two fields of LIS and history (610 papers), among which 240 papers were chosen by random partial sampling. The obtained results indicate that the level of precision (in the two mentioned fields) in “Nama” and “Namayeh” databases is 56% and 40%, respectively. Also, the level of recall (in the two mentioned fields) in “Nama” and “Namayeh” databases is 58% and 35%, respectively. In addition, the searching time in “Nama” and “Namayeh” databases is 1 minute and 13 seconds and 2 minutes and 13 seconds, respectively. Applying t-test to independent samples in this study showed that there is significant difference between the two databases regarding precision, recall, and searching time; correlation among these criteria is direct and significant between the two databases. The obtained results indicate that, in comparison with “Namayeh” database, “Nama” database has a more desirable status concerning the level of precision and recall, as well as searching time, and these good retrieval results may be attributed to use of thesaurus in indexing “Nama” database.Originality/Value: Based upon the study results, those who search information can better make decision in choice of a database proportionate to their needs; besides, database designers can find out which controlled language is better for database development in organizing the resources.

After the development of the web environment, the display types of thesauri were affected by the abilities and features of this environment. This article makes an effort to review the display types of thesauri especially in the web environment and to study the capabilities and effects of this environment on previous types of display. It also briefly reviews some of the web-based thesauri.The findings of this research show that, although the web environment has brought about some changes in web-based thesauri in terms of accessibility, the use of different types of display without being worried about space limits, the ability to simultaneously see two or several display types and to see several levels of hierarchy; thesauri of the web environment still face challenges for which proper solutions must be found.

The present paper reviews the methods for compiling and constructin online thesauri from two general approaches of computer-aided thesaurus construction and computerized thesaurus construction. In the discussing the construction of online thesaurus with help of computers, use of deduction engine for determination of terminological relationships as well as the concept approach for construction of online thesauri were studied and the practical stages of online thesaurus construction were reviewed. In the computerized approach for construction of online thesauri, textual methods, methods derived from WordNet Hierarchy, clustering and Self-Organized Mapping Techniques were studied.

The purpose of the present study is to explore the impact of new coming terms on the structure of the recent editions thesauri compared to the previous ones. The case of this research is the 14th and 13th editions of ERIC Thesaurus. The finding's indicate that the new terms affect the structure of thesaurus in terms of omission, change, or addition of the terms interrelations. But the highest Impact occurs on the hierarchical relations. The final results show that there can be found no correlation between the quantity and complexity of the changes occurred.
